Hey all, I'm getting Logic Studio on my MacBook and am planning to use Mainstage on stage. Just a question, how do I output the sound? Do I use just the on board sound with an adapter to fit the ¼" plug? Is that sufficient? Or do I need an output device of some sort? The stage is pretty big, all sound goes through an Aviom system and through a central desk to the front of house. So I just wasn't sure if the inbuild output is sufficient? Anyone with knowledge on this? thanks!
